A stuck-open thermostat will constantly send coolant through the radiator, regardless of its temperature, causing coolant temperatures to drop and the heater to malfunction while traveling down the road. Find out why your car stalls and get tips to fix the problem yourself. Answer: There are some common issues that usually can be traced to this problem (but not the only ones): first, make sure the water pump is working properly.

You could make some makeshift ramps out of lumber etc. To find the thermostat, follow the upper radiator hose to the housing where it attaches to the engine. it will be chuggy/sluggish and rattle-y making me have to rev the engine a few times for it to settle down before I can even go anywhere. Check the circuit. Dealer did pressure test and that came back fine so no head gasket problem although don’t have a lot of faith in that since problem still exists and they thought thermostat would fix it. 2. On some newer vehicle models, getting access to a temperature gauge on the instrument cluster may be difficult. Turn the ignition switch On. Not just the overflow bottle but the radiator also. Be sure to run the heater for a while when you are driving here and there, something this can help bleed air pockets. P0300 - Cylinder Misfire Detected Random Cylinders Thermostat valves can fail in one of three ways: open, closed or stuck halfway. If the hose and engine feel a bit warm but not hot, the thermostat is likely stuck open and will prevent the engine from reaching operating temperature. Just trying to think of where i could go near me with a incline that wouldn’t have to sit for hours unattended. Look under the lid for the fuse box.

I wasn’t charged or anything for this so the only thing lost is simply the time of my car hanging out at the shop and not really having anything done to it. If the gauge still reads higher than "cold," replace the gauge. A faulty radiator fan may cause the temperature gauge to fluctuate. If possible, do this initial inspection after the engine has been running for more than 20 minutes, or as soon as your gauge indicates an overheating condition. A warning light won't come on unless the engine overheats. It is still possible that a head gasket leak into the coolant may not be found by a cooling system pressure check but if done carefully it will usually tell. Go over the tests in the post. If the check engine light is on, check for diagnostic trouble codes (DTC) first. It'll remain at around the middle of the reading scale, if the engine stays at operating temperature. Note: The procedure below requires grounding the wire that connects to the temperature sending unit. If it is okay, ground the gauge terminal where the wire connects to. If both upper and lower radiator hose have about the same temperature, coolant is not circulating (overheating) or the thermostat is stuck open (engine below operating temperature). Today service engine soon light came on. For instance, you may opt to use a 170-degree thermostat in place of the recommended 180-degree thermostat if you do a lot of towing, or a 190-degree thermostat if you want to pick up a bit of horsepower and increase heater output temperature. The temperature gauge on a car fluctuates because the car's thermostat is opening and closing. The general rule is to address the lower number code first. He has certifications in automation and control technology. See if you can hear any noises (worn bearing) coming from the water pump. If not, check that wire for damage. I have checked the oil per a friend’s suggestion for the milky/frothy and that isn’t there (will check later today for the sticky residue on the tail pipe). Is it the Temperature Gauge or Something Else? If you see coolant leaking, the system is running out of coolant and the engine is overheating. Just an update: after taking my car to my local garage, they decided to reset the check engine light to see if it comes back on with the same code to be sure it IS the O2 sensor before making the repair.

Consistently low coolant temperatures could only mean one thing; fortunately, the required parts are fairly cheap and easy to install. This article was written by the It Still Works team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information. A thermostat valve closes off the upper radiator hose when the engine's cold, forcing coolant to recirculate through the block until it warms up. Connect your voltmeter's black lead to the battery's negative (-) post. To submit your questions or ideas, or to simply learn more about It Still Works, contact us. Other vehicle models, especially Asian models, use two temperature sending units, one connected to the computer and the other one to the temperature gauge. Engine Temperature Issue - Please Help! The gauge should read "hot" or the warning light should come on. In some cases this may lead to detonation (a banging sound). All good suggestions, but also try replacing the thermostat. The water pump pulls water out of the water jacket and pushes it through the radiator tubes, and thus into the radiator. You can test the sending unit's resistance or voltage using a digital multimeter (DMM). Of course, the most common reason for an unusual reading on your car's temperature gauge is a problem with engine temperature. Mostly, your temperature gauge will be accurate. If the valve sticks in the closed position, coolant will constantly recycle through the engine without going to the radiator, causing the engine to overheat. The heater core is a kind of miniature radiator that sits in your car's climate control duct. Replace your coolant temperature sensor at home now using some common tools, a few minutes, and this practical guide. It was a PITA, but it worked. Pop the hood open and check the following: The coolant level should be at the Full Hot mark on the coolant reservoir tank.

The gauge goes up when the thermostat closes and the gauge goes down when the thermostat opens. Some vehicle models include a warning light. Brought it back to mechanic, changed thermostat and both things ok only part way home. Older vehicle models use a single temperature sending unit connecting to the temperature gauge. For a number of reasons, the part needed won't be available in my country for a few months. Obviously not thermostat problem. Locate the temperature sending unit.
